Teoriya Resheniya Izobreatatelskikh
Theory of inventive problem solving.
Started with Altshuller’s interest in
invention and work in Soviet Navy patent
TRIZ is a problem solving method
based on logic and data, not
Objectives of TRIZ are to define;
Generalisable patterns in the
nature of inventive solutions.
And the distinguishing
characteristics of the problems
that these inventions have
It is increasingly common in
1. Six Sigma processes
2. Project management and risk
3. Organizational innovation
Genrikh Saulovich Altshuller (1926- 1998)
Soviet engineer, inventor, scientist, journalist and
Somebody someplace has already solved this problem (or one very similar to it.)
Creativity is now finding that solution and adapting it to this particular problem.
Basic Principles of TRIZ
There are three primary findings of this research;
1. Problems and solutions are repeated across industries and
2. Patterns of technical evolution are also repeated across industries
3. The innovations use scientific effects outside the field in which
they were developed.
In the application of TRIZ all these findings are applied to
create and to improve products, services, and systems.
Tools of TRIZ;
- 40 Principles
- Contradiction Matrix
- 76 Standards
Essentials of TRIZ
200,000 patent abstracts
40,000 patent abstracts (innovative patents)
39 Standard technical characteristics
40 inventive principles
изобретательских задач – АРИЗ
algorithm of inventive problems

ARIZ is the central analytical tool of
Provides solution for complex
is a list of about 85 step-by-step
procedures to solve complicated
Contradiction(Key Concept of TRIZ)
Goal: Take as much passengers as possible?
Solution: Make the bus longer and bigger.
Problem: How will it turn in the narrow
Solution: TRIZ Segmentation.
TRIZ and Our Earnings
Samsung Electronics: Euro 1.5 billion, more than 3,000
Ford, brake systems.
Boeing Corporation Euro 1 billion in value added.
Intel company declared “TRIZ is an Intel's innovation
platform of the 21st century”.
Approaches which are
modifications/derivatives of TRIZ
TRIZ in New Product Development
The main purpose of TRIZ is same functions but ideal better, more innovative solutions
Simple TRIZ Examples
Example of Transportation beef
Result: With no extra cost, using avaible resources, system has been
reached shape which is desired.
Example of airplane’s landing gear
Result : after taking off, pull the gears inside and prevent the friction
Example of related focus on
real problem (PIZZA DELIVERY )
Everybody wants hot and crunch pizza.
How to solve this problem?
Design a perfect box according to
Both save pizza’s hot and crunchy
Even if order reach to customers
after many hours;
Example of The Boeing 737
A TRIZ problem solving team was called to the Boeing
factor in Seattle, Washington to see how the capacity
of the Boeing 737-100 could be increased.
The airplane engine is the moving
object. We would need the engine
air intake and the fuel injection
casing to be larger so the
improving feature is engine
volume. the but if we increase
the volume of the engine it will
decrease the clearance distance
between the bottom of the engine
and the ground (worsening
feature). The improving feature is
number 7.“Volume of moving
object (engine) and the worsening
feature is “3. Length (diameter)
of the moving object (clearance).
The engine intake area and the cowl with the fuel lines
make up the engine volume, thus an improving feature
will be the “7. Volume of the moving object” and the
worsening feature again “3. Length (engine diameter, i.e.,
clearance).” This intersection gives from Altshuller’s tool
of 40 Principles.

Approach to problems
TRIZ provides a structured approach to problem solving,
TRIZ prevents erratic brainstorming and search for
TRIZ helps identify and clarify problems and provide good
TRIZ helps to generate more innovative ideas.
Innovation and new solutions
TRIZ provide breakthrough innovation and
The resolution of problems and arriving at
innovative solutions was achieved in
TRIZ provide respondents with a view of
how technologies would evolve in the
future and be put into consideration while
planning for the future.
TRIZ appears to have an effect of improving the effectiveness of
It provides a common language for problem solving within the group
Modern TRIZ should not only be seen as a methodology for
solving engineering problems or a new product
main ideas behind TRIZ become a powerful tool for
managing knowledge and solving problems that contain
contradictions in many areas
